INDYECATING DEVTCE PHONOGRAPHY AND ITS Al'PPLICATION.

Application filed June '15, 13%. Serial No. 2502,2224.

To all whom it may concern Be it known that I, Mionnn on Buzzes, acitizenoi' the French Republic, residing at- Paris, in the {Departmentof the Seine, France, have invented contain new and usei'ul improvementsin Indicating Devices for Phonography and Their Application, of whichthe following is a specification.

This invention l'GfGTSlOfin indicating arrangcmeut which permits offollowing by reading-the ordinary emissions of a phonographsimultaneously with the production of the said sounds.

"With this object in viow the essential element of the indicating deviceconsists of a flexible band unwound by clock-work and inscribed with-thevarious parts the piece to be performed, for example, the song, thewords and the accompaniment. {in this band the music or the words arenot written as is usual with scores, that is to say, that instead of thespace existing between the various-bars depending on the number of signsto be arranged between the said burs, this inscription solely dcpciulson the period of time occupied in executing the sounds or syllablesinclosed between two consecutive bars. In other words, when the band isunwound, the arious musical signs, Oliill, various syllables of thewords, pass {before a fixed pointer, for example) exactly according tothe various alterations of speed imparted to the whole according to theexpression it is desired to impart. it. can consequently be understoodthat by following the unwinding of the indicating bend, the performers,for example, the singer and the accompanist, are guided in "theexecution their respective parts, so as to .be always together, and nnyhesitancy or inaccuracy in the execution is thereby avoided. Whatr thecase may be, the indicating hand an. generally comprise one or morelines referring to the melodious part or to the de .claihatory part, andone or more other lines referring to the. accompaniment. in orderpractically to carr 1 out the special rhythmic and expressiveinscription referred to above, and at the some time to obtain agreementbetween the various parts, for the production of the hand, it will benece sary to employ an arrangement for inscribing the i rhythm, whicarrangement is described inrther on. Theindioetor, formed in themanner-just described, its capable of various up plicationsfitherii'l'one or in coinbinetioi Specification of Letters Patent.

Eflntented June llfilt h with other musical apparatus, more particularly the phonograph. In this latter case, by seporately -.recording thesong and the accompauimont, iit permits the singer being accompanied bythe phonograph, or, an accompanist to eccompnny a song by thephonograph.

I shall now desoribeiniy inventionwith relorcnce to the accompanyingdrawings, showiup; the musical indicator referred to above as applied toa gramophone, and provided with the special arrangement for theproduction of the rhythmic bands of the indicuter.

'ihe arrangement shown in Figs. 1 to 3 it-Shae (f).

of the -hand (h) is controlled by a double pin-wheel (e) fitted loose toa shaft which is rotated and at thedesired moment rotates the pin-wheel(e) by the intermediation of a couplino disk (g). This disk (g) canslide along the shaft. (f) but is always carried around on the-rotationof thelatter. The inner surface of-the disk (9) is provided with slotsor recesses (g'), which 1 0 are for the purpose of meshing withprojections (6) provided on the adjacent surface of the pin-wheel.

The shaft (f) is" rotated y clock-work or in anyother suitable manner.For the case in which the indicating band is fitted to a phonographicapparatus, as in the exa-rnpleshown in the'drawings, the shaft (f; wouldbe rotated b' the driving shaft (h of the phonograph, hy theintermediationof any suitable transmission whatever; for exainple,'theshaft (It) may be provided with a worm (71,) meshing with a worm-wheel(2'), fixed to a pinion (2") which latter meshes with a cog-wheel (fkeyed the In order to facilitate the reading of the band, moreespecially when the latter is in scribed with the song and theaecompaniment, the guide (a) may be inclined at a so variable angle, asshown in' Figs. 4; and 5; in this case the shaft would consist of twoparts, connected together by beveled pinions (a 4- v r In, order to beable to easily d sengage the indicating band (6) from the ln-wheel (e),the guide (a) can be turne sli htlyaround the fixing screw (Z), and ishe din position at its other extremity by a set screw (m). The receivingreel (d) has imparted 40 to it a. rotary movement whichcanhe controlledeither by the pin-wheel (e) or by'the clock-work of the apparatus.',.The side" (a) furthermore-consist of one or more of the guide (a) isprovided with a pointer (nfmovable-along-a rod (0) so as to be a5brought in front of the desired spot of the indicating band, In order toproduce this band, it is first-necessary to inscribe the rhythm of the,piece; with this object. in view, the band actuated as has been deascribed, is unwound, and'by 'means of a style on the emission of eachnote or. each syllable, a line. is traced on this band and is prolongedduring the whole period through which this note or syllableis sustained.This 5b succession of lines, some-longothers short,

constitutes a graphic indication. of the rhythm of the piece. I l

In front of the starting point oteach line, C thecorresponding notesorysyllabl'es' are inscribed on the band, and beneath the same- 1"theflcorresponding notes vof the accompani-v ment. For inscribing 'thisgraphic record the .present. arrangement may consist of a style (p),fitted to the arniaturetq) of an electromagnet (g) in the circuit ofwhich'a manipmatelyerpendicular to the line during t note or'syllable.is sustained.

Whenthe current is cut off from the'electro-magnet (g'), the style -(;u)will be in its osition of rest and will then inscribe on the and astraight line X-X. On each emission of notes or syllables the lever ofthe manipulator (1') will be pressed down, thereby closing the circuitof theelectro-magnet (g), the armature (g) of which will be attractedand the style (p) will first trace a small line a rogiv e whole periodduring which the note or syllable is sustained the manipulator (rl-iskept pressed down, and the style will then trace on the band a line arale] to the line X-X, and the length 0 which will depend on the period oftime that this The tracing point of the style (p) may. be mounted-on anarrangement which ermits 'of removing the band of paper whbnever no lineshould beinscribed on the band.

Another auxiliary style (8) mounted on a spring and intended to beoperated directly y hand, may be arranged in front of the style gp).This second style (a) ma be utilize as a substitute for the style p orfor markin on the band certain re erence lines inten ed for example, inthe casein which an error has beencommitted in [recording the graphicrecord by means of the first style actuated electrically, to permit ofimmedlately finding on the and'the place where the'error has been made.The rhythmicgraphic record thus inscribed on the band may be preservedafter the inscription of themusic and words, or it may be rubbed out.-The present apparatus will b'epro vided or not with the arrangement forin? scribing the rhythm, according to the 1e The apparatus for producingthe band may printing disks (:3), inked 'by-roller (14) (Figs 6 to 8)and intended forthe purpose of tracing the musical stafl 'or staves onthe band (6),

The whole of the arrangement can be completed by a desk (It) for thepurpose of receiving, for example, the score containing the piece sungby the phonograph when it is desired to control the piece inscribed onthe score and the inscription'of the rhythmic band.

In the modification shown in Figs. 17 to 21, the pin-wheel (a) iscovered over byxcap or case which can turn around ,its pivots 2; thiscap IS'f'OlihB purpose of maintaining the rhythmic band (7)) in contactwith the. ,upper part of the pin-wheel (c); this arrangementpermits atthe commencement of an operation of more easily placing the band (6) inposition, inasmuch as it suffices to raise the cap I, to place the freeend of the bandontheupper art of the wheel (e) and to push down tie capI again. This modification, furthermore,comprises a spe cial device foractuating't-he engaging and disengaging ear of the pin-wheel (c), and

This arrangement is combined so as simultaneously to I control theengaging or the disengaging of tive spindles (6 d), and are rotated bythe said pin-wheel and the reel so as to avoid the possibility of anywrong manipulation.

The pin-wheel (a) and the receiving reel- (d) are both mounted loose ontheir respectwo couplings (g, (i These latter are respectively fixed totwo pulleys (e, d), connected together by transmission belt or cable ((2The coupling (g) is firmly attached to the shaft (e as regards therotary movement, butcaribe freely displaced lon- 'gi'tudihally alongthis shaft.

The displacements of the two g, d?) arecontrolled by levers (g', d). and these latter are actuatedsimultaneously by a single cam 13 keyed to aspindle l provided with amanipulating lever 5 According as the latter is moved in one or theother direction, so will the couplings (g,

The present system of rhythmic inscription is capable of numerousapplications.

The present apparatus can be advanta .geously employed for recordingphonofgraphic disks.

At present when anartist sings or speaks in front of a phonograph forthe purpose of recording a piece, he is constantly preoccupied with thenecessity of terminating his piece within the required time, and if therecording of the piece has not been finished at.-

without disk or cylinder, while at the same time rotating a band onwhich the operator 1y while the photraces the rhythmic graphic record ofthe song to be recorded by scanning on the manipulatorthe syllables ofhis song. If the piece is performed within the required time, thesyllables may then be inscribed on the band in front of thecorresponding lines on the conof the graphic record; while i trary, thepiece has not been terminated within the required time,- the artist willhave to begin again, but this fresh performance of the piece will nottire hi1n because, as has been stated, he is only singing softly,

without effort and consequently without fatigue.

Then the rhythmic graphic record of the piece performed hasbecn obtainedwithin the required time, the wax disk is placed on the phonograph, andthe band inscribed withthe graphic record is introduced into theapparatus. The phonograph is then started, and the artist performs thepiece atthe top of his voice .as the band is unwound at the same speedas during its inscription,

he has no longeiy to worry himself about the time allotted to him,onlyhaving to sing according to the inscriptions of the band passing infront of his eyes. I

The present apparatus may also be used for any kindof instruction,because the agreement which it supplies between the signs read and'thesounds heard produces I the brain an intimate correlation betweengraphic record of the these signs and these sounds and by frequentrepetition this correlation can be fixed in the mind.

The present apparatus can be used for thefinstruction of languages;thus, the phonograph might pronounce a series of fortion, as describedabove. Bythis method-of teaching, the auditor would be rapidlyfamiliarized with the signification of the words or with theirpronunciation.

In the case in which the indicating ban has to be read by severalpersons at one. and the same time, the apparatus. willbe of largerdin'iensions and the band will be e.\' oscd at a suitable height abovethe ground. Vith the present indicating apparatus mechanical pianos ororgans may be. employed for accompanying a piece performed by an artistor by a phonograph.

As previously described,

a rhythmic inscribedf then according to this graphic record will bedetermined the position of the perforations of the cards or rolls ofthese mechanical pianos or organs so as to establish the agreementbetween the accompaniment and the song; it will then sufficemechanically to conncct the actuating mecha-' nism of the rolls of themechanical piano or organwith that of the phonograph, or the actuatingdevice of a rhythmic band in accordance with that which has served tomanufacture these rolls. in order' to obtain synchroniszn between theaccompaniment executed by the mechanical piano or organ and the piecesung by the phonograph or artist. In the casein which the piece isperformed by an artist, itsnfiices for the latter to sing. speak or playwhile followin the. passage of the rhythmic band.

[be present imlicating apparatus may also be applied for svnchronizingthe moiement of a kinematograph with those of a phonograph in thefollowing manner. The artist will be kinematographed or' howgraphedkinematographically while singing softly during which time a rhythmicgraphic of this song will be inscribed on the band. This band is thenunwound in the apparatus at the same. speed, and the artist sings outiece would be first loud before the phonogra h while followingthe'inscriptions of tie band passing along in front of him.

.It is to be understood that the term phonograph as hereinafter usedinthe lent apparatus of other names, the nature of which apparatus hasbeen pointed out elsewhere in this specification, It is clear also thatthe present indicating apparatus for recording the rhythm is capable ofnumersaid band apressin ous other applications, and that the shape,dimensions and arrangement of detail may vary according to theapplications.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is:

1. In a sound producing device, a movable support for a sound producingrecord, a band run in synchronism with said support, and electricallycontrolled means for img on said band, a graphic record for indicatingrhythm,

2. Ina phonograph, a movable support claims issutiiciently broad toinclude-equivafor a sound producing record, a band run "synchronouslytherewith, and clectro-magnetically controlled means for impressing ongraphic record for indicating rhythm;

3. In a phonograph, a movable support for a sound producing record, aband run synchronously therewith, and key controlled clect'ro-magncticmeans for impressing on said band, a graphic record for indicatingrhythm.

4. The combination of a phonogra )ll ha\-- ing a driving mechanism, of amovable member driven from saiddriring mechanism and having a surfaceadapted to receive a graphic record, electrically ccmtrolled means forimpressing a graphic record upon said surface including a markerlaterally morable with respect to said surface, and a manually operablemember for controlling said electrically controlled means, the length ofthe graphs depending uponthe rate of moveinent of the movableme1nber.:md'thc successive operation of said manually operable member.

In testimony whereof I aliia' my signature in. presence of twowitnesses.
